IMPROVED IVIASH-TUB AND VAPOR-COOLER.

Specification forming part of Letters Patent No. 87,64 0, dated March 9, '1869.

operation ot' the same, reference being had to I and exact description ofthe construction and the annexed drawing, making a part of this specification, in which the ligure is a perspective view of the machine, cut away in part to In the tigure, O is a cylinder of metal. D D is another cylinder, placed inside ythe one C and made fast to it at the bottom.

A is a tube passing through the tops of both cylinders to the interior of D D, and is calculated to admit the vapor to be condensed.

Pis another small tube, passing from the inside ot'D D through the bottoms of D D and C, and is intended to draw oft' the condensed y vapor with.

R is a tube passing from' the space between the two cylinders at the top of the cylinder O.

M is a pipe passing from .the bottom of C, from between O and D D, underneath and in `front of the machine, and is the pipe through which the cold air is blown to condense with.

F is a pipe passing loosely through the bot- 1 tom of O and D D, and connects with M at the wish to use the machine for cooling mash.

To these joints are connected the tubes T T, which connect to the cross-piece E, to which is connected the tube B, which passes through the top ofthe cylinder C. This whole series of tubes is caused to revolve by the wheel K, made fast to the lower end ofthe tube F.

Now, in order to condense vapor, blow air in at the tube M, which will fill the series of tubes W W, N N, F, S, T T, E, and B, also the cavity between the cylinders G and D D. In this case the holes at the joints N N must be closed, and the vapor is passed in at the tube A. When the machine is used in cooling mash the holes at the joints N N are opened, and the air is introduced, as before, through the tube M, and the series of tubes attached to F is set in motion` by the wheel K and stirs the mash, at the same time cooling it.

Now,what I claim, and for which I ask Letters Patent of the United States to be granted me, 1s

1. The construction of the revolving tubes S, F,N N, W W, T T, E, and B, as above described, and for the purposes set forth.

2. The construction of the two cylinders D D and O, in combination with each other and in combination with the tubes M, R, and A, as above described,and i'or the purposes set forth.

3. The combination ot the cylinders O and D D, together with the series ot' tubes F, N N,

W W, S, T T, E, and B, as above described, and for the purposes set forth.
